WebVR and Cesium

Are there any current demos/examples of Cesium and WebVR available that show the capabilities on iOS?
I have been searching and have found WebVR demos that work on iOS and cesium demos that work on iOS but not the two together.

We are not tied to WebVR just need to be able run cesium effectively in VR mode on iOS.

Any insight is greatly appreciated.

Have you seen the Cardboard Sandcastle demo?
